The Stylite PassivehausFoundationInsulation system was introduced to the client, who quickly saw the benefits it offered. SPI worked closely with the client to specify and design the foundations to be fully compatible with a Structural Insulated Panel (SIPS) wall system which also incorporated Stylite Plustherm insulation.

The Stylite PassivehausFoundation system comprises lightweight Expanded Polystyrene (EPS) units contour cut off-site and delivered to site ready to lay. “L” shaped high density units are positioned around the perimeter whilst flat EPS boards are used to complete the first layer. A second layer of EPS boards are then laid in a break bonded pattern to create a channel ready for the concrete to be poured in.

Having an insulated foundation system meant that any cold bridging at the ground and wall junction was eliminated whilst the super low U-value of 0.010 W/m2K met the clients requirements to future proof the homes. The holistic design solution met the Passivehaus standards demonstrating the homes also have reduced energy usage and low energy bills.

Brian Monaghan, SPI National Sales Manager said; “Our clients vision to build two homes to the Passivehaus standards has been made possible by the use of some innovative products such as the Stylite PassivehausFoundation system. Our design team worked hard to provide a great solution, and once on site it proved to be very quick and easy to install.”
